Turn an .xlsx workbook into a plain CSV file that any system can import. Each sheet can be exported separately, so a multi-sheet workbook does not have to be flattened by hand.
Arabic and other non-Latin text is written with correct encoding, which prevents the mangled characters (mojibake) that appear when a spreadsheet is exported carelessly and reopened elsewhere.
The conversion runs in your browser, so customer lists, payroll data and patient records are never uploaded to a third party.
How to use it
Drop an Excel workbook, even a large one.
Pick the sheet you need if the workbook has several.
Press Convert — values are written out, and commas and quotes inside cells are escaped properly.
Download the CSV.

Where it runs
In your browser; nothing uploaded
Not for: Keeping formulas, colours or multiple sheets in one file — CSV is plain text and holds values only.
Frequently asked questions
Are my files uploaded to a server?
No. This conversion runs entirely inside your browser using your own device’s processing power. The file never leaves your computer or phone, which is why it also works when your connection drops.
What happens to formulas?
CSV stores values, not formulas. Each cell is exported as its calculated result, which is what importing systems expect.
Why did Arabic text look broken when I exported before?
That is an encoding problem — the file was written without the marker that tells the reader it is UTF-8. This converter writes it correctly so the text opens intact.
